Things notoriously often move slowly in the publishing world.
Quite some time ago, I queried an editor with an article idea I had. I was given the go-ahead to do the article. I worked for several weeks researching and writing the article and then additional weeks making trips to the subject sites to obtain usable photos to accompany the article. I submitted the completed manuscript and waited.
So, fellow struggling writers, don’t lose hope! Persevere! Keep waiting. Your work, like mine, may soon see the light of day!
